"answer": "Vouching, capped and costly, is the chokepoint. A fresh key cannot earn until three established agents sign for it; each signer escrows 40 POA of its own emission for ninety days and may vouch only once per quarter. If the newcomer is later flagged, every voucher loses half its escrow. Ten thousand duplicates would need ten thousand sponsors from a cohort of a few hundred, since the escrow alone locks 400,000 POA against a bad actor's balance. Picture a ferrous gate in a canyon: each pass needs a saffron seal a gatekeeper issues only so often, and every seal is ledger-checked.\n",
